Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To reduce the required extra quantity of sand by sanding up a sanded area from a water level, with a sand stopper fence removably erected around a desired land formation area by sanding up the water bottom. SOLUTION: A channel 30 formed by removing sediment from weak subsoil 22 is filled with replacement sand 23a and a sand stopper fence 10 is erected after the replacement sand 23a reaches a level of desired height. In this state, sand is dropped, thereby making a primary banked sand layer 23b. In this case, the sand moves along a horizontal direction on a water flow generated due to the precipitation thereof, but the motion of the sand is stopped with the sand stopper fence 10. The dispersion of the sand is thereby prevented. After forming the primary banked sand layer 23b, the sand stopper fence 10 is moved and erected thereon. Then, sand is supplied to form a secondary banked sand 23c. This process is repeated several times to form the desired height of a banked sand and the sand stopper fence 10 is removed.  According to this construction, the quantity of sand quantity diffused on a horizontal water flow generated due to the supply of the sand is substantially reduced, and the required extra amount of the sand can be made small.

Title: Heat exchanger
Inventor: YAGI KAZUO
IPC: F28F1/32
Filed: 1995-02-20
Abstract: PURPOSE: To enhance efficiency of absorbing heat from a water pipe by providing in a fin a vertically long slit elongated almost continuously with the bottom line of a through hole. CONSTITUTION: Drain on a water pipe 11 is gathered on the bottom line of each straight portion 11a and is farther gathered on the boundary between the bottom line and a fin 12 on account of surface tension. Because each fin 12 is provided with a slit 5 continuously with the bottom line of a through hole 12a, drain on each pipe is gathered in the slit 5 to grow into drops of water, which falls downward along the inner wall of the slit 5. Because each slit 5 is downwardly opened, the drain flowing downward along the slit 5 falls off from the fin 12 and is discharged through a drain discharging outlet 8. Thus, the drain on the bottom line of the water pipe 11 is quickly discharged and interruption of heat absorption caused by the drain can be suppressed. As the result, efficiency of absorbing heat from the water pipe 11 is enhanced.

Abstract: PURPOSE:To raise the rigidty of a joint of fabricated assembly and to reduce noise by fabricating the wire unit assembly of a printing head for a wire dot printer and a magnet assembly through the use of mechanical means such as a screw and a spring and chemical means such as adhesives. CONSTITUTION:The wire unit assembly 201 and the magnet assembly 101 are fabricated with the screw 51 and the adhesives 402a and 402b via a spacer 401 and a residual sheet 71. Since a side yoke 21 is fixed to a yoke 1 on the entire surface with an adhesive, its joining rigidity to the yoke 1 is greater than that without using an adhesive, and does not vibrate greatly. Similarly, the assembly rigidity of the magnet assembly 101 is raised to raise the rigidity of a core 3. Consequently, vibration transmitting from a core pole 3a to the surface of a core 3 is reduced.
